Prerequisites
-------------

Credentials Setting
~~~~~~~~~~~~~~~~~~~

To use Tacker CLI, you need to configure the credentials, please change the ``username`` and ``projectname`` to be executed according to your environment.

.. code:: bash

   $ source ${devstack_dir}/openrc admin admin

If you want to access Tacker via API, you need to get auth token by following procedure below.

.. code:: bash

   # Create request body for issuing access token.
   $ vi get_token.json
   $ cat get_token.json
   {
      "auth": {
         "identity": {
            "methods": ["password"],
            "password": {
               "user": {
                  "domain": {
                        "name": "Default"
                  },
                  "name": "admin",
                  "password": "devstack"
               }
            }
         },
         "scope": {
            "project": {
               "domain": {
                  "name":"Default"
               },
               "name":"admin"
            }
         }
      }
   }

   # Issue auth token for accessing via API.

VNF Package
~~~~~~~~~~~
Create and upload the VNF Package that you want to deploy by following procedure below.

1. Prepare VNF Package.
   The sample VNF Package used in this guide is stored in ``o2/tacker/samples/packages/vnf_v2`` directory.

   .. code:: bash

      $ git clone https://gerrit.o-ran-sc.org/r/smo/o2
      $ cd o2/tacker/samples/packages/vnf_v2
      $ ls
      BaseHOT  Definitions  input_param.json  Scripts  TOSCA-Metadata

      $ zip sample_vnf_package_v2.zip -r BaseHOT/ Definitions/ Scripts/ TOSCA-Metadata/


   About details to prepare VNF Package, please refer to `Prepare VNF Package`_.

2. Create and Upload VNF Package.

   * via CLI command:

     .. code:: bash

        $ openstack vnf package create

Instantiate
~~~~~~~~~~~
Instantiate a VNF by specifying the ID of the created VNF Instance and a file path of input parameters.
V2 API allows you to insert VIM connection information directly into the instantiate input parameters.

.. note::
  Please change the parameters in ``input_param.json`` to suit your environment.

.. code:: bash

   $ cat input_param.json
   {
     "flavourId": "simple",
     "vimConnectionInfo": {
       "vim1": {
         "accessInfo": {
           "username": "admin",
           "password": "devstack",
           "project": "admin",
           "projectDomain": "Default",
           "region": "RegionOne",
           "userDomain": "Default"
         },
         "interfaceInfo": {
           "endpoint": "http://192.168.121.170/identity"
         },
         "vimId": "defb2f96-5670-4bef-8036-27bf61267fc1",
         "vimType": "ETSINFV.OPENSTACK_KEYSTONE.V_3"
       }
     }
   }


* via CLI command:

  .. code:: bash

     $ openstack vnflcm instantiate ae844932-730a-4063-ad1d-7e3f7f9d82d1 input_param.json --os-tacker-api-version 2
     Instantiate request for VNF Instance ae844932-730a-4063-ad1d-7e3f7f9d82d1 has been accepted.

* via API:

  .. code:: bash

     $ curl -i -X POST ${TACKER_ENDPOINT}/vnflcm/v2/vnf_instances/$VNF_INST_ID/instantiate \
            -H "Content-type: application/json" -H "X-Auth-Token:$TOKEN" -H "Version: 2.0.0" \
            -d @./input_param.json

You can verify that the deployment was successful in the following ways:

1. Verify that the VNF Instance displayed by :command:`openstack vnflcm show` command is as follows:

   * ``Instantiation State`` became ``INSTANTIATED``.
   * Deployed resource information is stored in ``vnfcResourceInfo`` of ``Instantiated Vnf Info``.

   * via CLI command:

     .. code:: bash

        $ openstack vnflcm show ae844932-730a-4063-ad1d-7e3f7f9d82d1 --os-tacker-api-version 2
